【Abstract】 The common sealing structure of unbonded flexible marine pipe end fitting is introduced. The sealing performance of the end fitting is numerically analyzed by Abaqus. The sensitivity of the sealing performance of sealing ring on the different structure parameters of sealing structure is studied,and the rule is obtained which reflects the effect of sealing structure parameter change on the sealing and mechanical performance of the end fitting. The results show that the key design parameters of the sealing structure are the cone angle and curvature radius of sealing ring,and the loading displacement,etc.更多还原
